# AI advises closing and taping all windows before a hurricane to prevent shattering (pressure differential and shard risk)

## Root Cause

Taping windows does not prevent shattering; it creates larger, more dangerous shards when the glass breaks, and sealing windows can cause pressure differentials that blow out the structure when the storm passes.

## Workarounds

1. **Install impact-resistant windows or permanent storm shutters before the hurricane season. These are the only reliable protection against wind-borne debris.** (95% success)

2. **If shutters are unavailable, board up windows with 5/8-inch plywood cut to fit, anchored with screws into the window frame.** (85% success)

3. **During the storm, stay in an interior room away from windows and glass doors. Do not open windows or doors during the storm.** (90% success)

## Dead Ends

- **Using duct tape in an X pattern on all windows** — Duct tape does not strengthen glass; it only holds shards together, creating larger projectiles when the window breaks (95% fail)
- **Closing all windows tightly to prevent wind from entering** — Sealed windows create a pressure differential when the storm passes, causing the roof to lift off and windows to blow outward (85% fail)
- **Leaving one window slightly open to equalize pressure** — This is a myth; the pressure differential is not significant enough to matter, and the open window allows wind and rain to enter (90% fail)
